This invention relates to machinesfor marking shoe upper sections or similar pieces of sheet material, particularly for performing the method of marking described in theEdwards .Patent No'. 1,639,332, dated August 16, 1927, and is adivision of my copending. application. Serial No.'.611,355, filed May 14, 1932, now U. S.'.Patent No..1,972,860, dated September 11, 1934. J

In the. manufacture of shoes, particularly womens shoes, it is customary to apply ornamental designs to the. shoeuppers, as by stitching,.perforating or embossing. Present fashions demand that shoe uppers be made of leather, textile fabrics such as silk, satin or velvet-and various other kinds of sheet material; }Usually,-the orn'amental designs are applied to the cut-out's ec tions of the uppers before they are assembled'in thev shoe; and in the case-of stitching,'-thedesigns are first marked on the shoe uppers and the marked designs are then followed in the-stitching. As explained in said Edwards patent the'design may be impressed upon the shoeupper-section or similar article of sheet material, by a marking plate, on whichthe desired pattern is formed by bosses punched from the material ofthe plate and disposed in lines, rows or; other arrangements to delineate the pattern. The marking plate is then impressed upon the shoe upper section or other piece of work to be marked,with a-transfer sheet against the opposite side of work, and the pattern displayed by thebosses will then be printed or impressed on the work. A similar method may be used withoutthe transfer sheet for merely embossing a piece of leatheryin which case the marking plate will be embossed inaccordance with the desired design, or for perforating the work, in which case the marking plate will be made with bosses in the form of cutting punches of such shape and arrangement as to cut holes or perforations in the work, shapedandarranged according to the desired design. p 7

Printing or marking, perforating andembossing, whether used separately or in various com binations at the same time, are all included in the expression marking as herein used; and the term marking plate is used todesignate the plate for applying the design to the work whether the plate is constructed for printing from'a transfersheet, or for perforating, or-for embossingfor for any combination of these operations.

One object of the invention is'to provide a marking machine having a normally inactive reciprocable press member which is automatically operated to impressithe desired; design on the work when. a platen; supporting the .workcand .the

v shifted to operative position under the press marking'plate, is moved'into operative relation to the press member; and to stop the pressmember when the platen is moved away" from the press member.

Another object of the invention is to'provide means by which the markingplate is automatically controlled so as to rise or move away'from the platen to permit the placing of the article to vbegmarked upon'the platen or permit it tobe removed'from the platen,when the platen is shifted out-from under the press member, and to move the marking plate into operative position overlying'the work on the platenwhen the platen is member.

. Other features of the invention are mechanism for automatically advancing the transfer sheet each time the platen is moved in and out of operating position with relation to the press member; means for detachably and interchangeably mount- 20 ing the marking pl ate 'onthe platen and for correctly-positioning the same thereoniwork-positioning means associated with the platen; and

the mechanisms for controlling and actuating the ,various parts. 25

Theseand other features willbe herein more fully 'descri'bedand particularly pointed out in the claims.

sectional detail on line I3-I3 of Fig. 16 is an elevation of the locking bar forma ing part of the locking plate holder shown in:

Fig; 12.

Referring first to the form of machine shown in figs. 1 to 11, the frame of the machine consists of a base I0, adapted to rest upon and be secured to a bench or similar support, and an-upper frame II in the general form of an arch.

The base III is provided at opposite sides with guideways or grooves I2 within which the worksupporting platen, indicated generally at I3, is mounted to slide forward and backward into and out of operative position with relationto a reciproeable plunger or press member 52, carried by the frame II. The platen I3 is provided at its front end with a handle I4 by which it may be manually moved back and forth along the ways I 2. In the drawings the piaten I3 is shown occupying its outermost position away from the press member, in which position the machine is at rest. The body or bed I5 of the platen is preferably a rectangular casting. Near each corner it is formed with a vertical hole I6 (Fig. 6) whose upper portion is of smaller diameter than its lower portion. The lower end of the hole I6 is closed by a plug H which serves as an abutment for a coil' spring I8 by which a plunger I9 is yieldingly supported with its upper reduced end 20 projecting above the top surface of the body I5 of the platen.

Resting on top of the platen I5 is a removable work-positioning plate 2| preferably made of cardboard or similar sheet material and provided near each corner with a small aperture reinforced by an eyelet 22, each eyelet being adapted to be fitted upon the upwardly projecting reduced end Thus the plungers I9 serve to hold the work-positioning plate 2| in a definite position on top of the platen I5 so that it will not be displaced laterally but can readily be removed when desired. The work-positioning plate 2! is made with a cut-out or recess 23 (Fig. 8) so shaped as to receive and properly to position the pieceof work to be marked,

' such as the vamp or forepart of a shoe upper 24,

or other piece of sheet material. As herein illustrated the cut-out 23 of the work-positioning plate 2| is formed with opposite ,side edges 25, 25 to engage the opposite side edges of the, sheet article 24 to positionthe same laterally, and with end edges to engage the outer end of the article 24 thereby to position the same longitudinally. It is not necessary that the cut-out 23 should exactly conform in all respects to the shape of the article. to be marked but it must be of such shape and dimensions that it will receive the article to be marked and will fit it sufi'iciently closely at a sufilcient number of points to position it definitely and accurately to be properly operated upon by the marking plate. It will be understood that for each different shape and size of article to be marked a different work-positioning plate 2| will be used having a cut-out adapted to the size and shape of the work in question.

Near the inner end of the platen I5 (Figs. 2,

5', 8 and, 11) is a marking plate holder indicated generally at 26, comprising a transversely disposed rock-shaft 2'! which rests at its opposite ing ends of the rock-shaft 21 are held within the sockets 28 by means of detent plates 29 secured in position against the opposite sides of bracket I5 by screws 3E. The screws 3|! occupy slots formed in the detent plates 29 so that byloosening the screws and retracting said plates the holder 26 can be removed from the platen.

Secured to the upper flattened side of the rockto provide a row of spring tongues 34 each of which is embossed to provide a rounded boss or projection 36 upon its under side (Figs. '7 and 8).

The marking plate, which is detachably secured to said rock-shaft, is shown at 3! and is preferably made of a piece of sheet metal such as galvanized iron, embossed or otherwise formed to provide marking projections or bosses 38 on its under side (Figs. 8 and 9). The marking plate 31 is of such shape and size as to enter the recess or cut-out 23 of the work-positioning plate 2|,

and is of a shape conforming at least approxi-' mately to the shape of the work. At its inner end the margin of the marking p1ate31 is bent at right angles inopposite directions on two parallel transverse lines to provide a step 39 and a lip 40 (Figs. 7 and 16-), the lip 40 being parallei but oil"- set relatively to the body of the marking plate.

The bar 32 forming part of the holder for the marking plate is cut away or stepped upon its inner under side to provide a groove 4i between the bar and rock-shaft 21 into which the. lip 40 of the marking plate is inserted. Along the margin of the marking plate 31 near the step 39 there is provided a series of'holes or sockets 42, each of which is adapted to receive and engage one of the projections 36 on the tongues 34 (Figs. '7 and 10) when the marking plate is attached to the holder. In assembling'the marking plate on the holder the lip 40 is inserted in the groove 4| and the plate then pushed home, whereupon the spring tongues 34 will yield until the projections 36 snap into the sockets 42. In removing the marking plate from its holder it is necessary only to pull it forcibly outward, the spring tongues 34 yielding to release the projections 36 from the sockets 42. Thus, the projections and sockets serve both to position the marking plate accurately on its holder and also detachably to secure the marking plate to the holder so that it can readily be removed and replaced by another marking plate of different pattern. It will also be apparent that if desired two or more marking plates can be attached to the holder side by side at the same time, which is sometimes desirable in impressing a plurality of patterns on different parts of the article to be operated upon.

, Alongside of the rock-shaft. 21 and parallel thereto is a take-up spindle 43, on which is wound one end of a transfer sheet 34 extending from a supplyspindle 45, on which is wound a supply roll 45 of the transfer sheet. The transfer sheet extends across the body I5 of the platen and then underneath the rock-shaft 21 to the take-up spindle 43. The supply spindle 45 is journaled at its opposite end in bearings provided upon a bracket 45 secured to the outer end of the body I5. The handle I4 is fastened to the bracket 46. A handwheel 4? is provided amazes:

atone end of the supply spindle 45andalhandwheel 43 is provided atone end of. the take-up spindle 43, by. which said spindles; respectively, maybe manually rotated if desired.

l The take-up spindle 43 is supported at its ends withinopensocket 50 (Figs. 5, 8 and '11) formed in thetop of the sides of brackets l. Normally the spindle 43 is :heldwithin. :thesockets by the detent'slides 29. .Eachdetent s1ide:29.is made with two hooks,1 5|. and '5Ie,.th'e. former serving tolock the rock-shaft '21. within 'its bearing socket 28 and the latter serving to lock 'the spindle 43 within its :bearing socket 50. When the detent slides 29 are retracted, which can be accomplished by loosening the screws 30, both the shaft ZIand the spindle 43 may be removed from g the .machine.

' To prevent accidental rotativezdisplacement' of the spindles 45; and. 43, leaf springs 48 and 49 fastened to the underside of the body I5 oftthe platen bear against the under sides of the rolled machine frame and normallyresting by gravity against a stop-stud. 98 projecting from the frame. The end of the pawl 96 is in the path of the lower side of ratchet wheel 95'so that -when-the manually moved platen reaches the limit of its outward movement away from the 'press member, the ratchet wheel 95 engagesthe pawl and is rotated to the extent of one tooth,- hereby advancing the transfer sheet the same distance. When the platen is thereafter shoved inwardly the pawl 96 is idly rocked-by the ratchet wheel and assoon asthe ratchet wheel passes out of engagement with the pawl the latter is returned by gravity to its' normal position againststop98. Thus,- each time the-platen is operated in andout its motion is utilized to rotate take-up spindl 43 the distance of one ratchet tooth thereby winding'up the transfer sheet 44 on spindle 43 and presenting afresh unused portion of the transfer sheet to the action of the marking plate for each operation thereof. A stop 53 (Fig; 2) at the side of the platen-'limits'the outward movement of the platen, as hereinafter more fully described, and the pawl 96 is sopositioned relatively to the stop that when the platen is arthe shoe upper section or other article which is to be marked in position within the recess 23 of the work-positioningplate 2 I; and that when the platen is shoved inwardly under the press memher the marking plate 31 willbe lowered to operative position over the work upon the platen so as to impress the'markings upon thework when the press mmber'is operated; Upon again withdrawing the :platen from its operative positioniunder the press memberthe marking plate is again swung upwardly or opened so that the finished .Ywork may. conveniently be removed by the operator from the platen and a new piece of work inserted in its place. Themechanism for accomplishing this will now be described.

Fixed to one end of. the rock-shaft 21, which carries the marking plate, is an arm or cam follower 54, (Figs. 3 and 8) extending upwardly at an incline to cooperate with a cam 55 (Figs. 1, 2 and 3), which is formed by an upwardly bent inclined end;of a lever 56 fulcrumed at 51 on top of the :base' In ofthe machine frame. Thislever is yieldinglyheld in normal position with the cam 55 in the path of arm 54 by means of a leaf spring 58 secured toithe side of the base III. The lever 56 is provided with a laterally and downwardly extending bracket 59'which engages the outer side of the base [0 and servesas a stop to limit the inward swinging movement'of the lever 56 under the influence of spring 58.

The freeend of bracket 59 is formed with a slot- 60 (Fig. 2), against the inner end of which abuts a pin 6| projecting upwards from the stop' bolt or latch 53. The stop "latch 53 extends through and slides in a hole in the base l0, into the guideway [2 for the platen and into thepath of stop shoulder 81 of the platen, andis normally urged by a spring toward its operative position. The stop latch 53 isfree to move endwise independently of the lever 56 but when the latter is manually swung outward on its pivot 51 by means of a handle 88 it acts through bracket 59 and pin 6| to retract the stop latch 53.

Ii The dam orabutment 55 is normally positioned so that 'when the platen is moved outwardly and is nearing the end of its movement in that direction the arm 54 on rock-shaft 21 engages the cam 55 thereby rotating the rock-shaft and swinging the marking plate 31' into its raised or open position; The shoulder 81 on the platen engages the stop latch 53 to stop the platen and hold the markingplate 31 in raised position while the platen is in its outward or inoperative position with relation to the press member. When the platen is shoved inwardly toward the press member the arm 54 moves away from the cam- 55 thereby-permitting the spring 62, aided by gra ity, to rock the shaft 21 inthe opposite direction and swing the marking plate 31 downinto operative position upon the .work. 24 which is held within the cut-out of the work-positioning-plate 2|.

Inasmuch as the marking plate 31 is a thin sheet of metal and is sometimes thrown upwardly rapidly and with considerable force by the engagement of arm 54 with cam 55, it is desirable to provide means to arrest the marking plate when raised to its elevated position andto prevent undesirablevibrations thereof To this end a wire bail 100 (Figs. 1 and 3) is provided, the two side arms of which are supported'by the frame l'l, with'the transverse stretch of the bail in a position to act as an abutment or stop against which the marking plate 31 strikes when raised to its fully open position. The spring 62 which urges the marking plate towards its lowered or closed position is attached at one end to one of the screws ilL-bywhich the detent slide 29 is held in positiomwhile the other end of the spring extends: partly around the under side of. rock-shaft 21 and is fastened theretoat The spring 62, therefore, which wedge 14 is disengagedfrom member 15 the latter is normally'undentension, at all times yieldingly urges the shaft21 in a direction to swing the marking plate 31. downward toward closed posi-' tion on the work.

When itis desired to. remove 'the platen I3 from the machine'itisionly necessary for the operator manually to swing the cam lever 56 sidewise and outwardly thereby removing the cam 55 from the path'of arm 54 and at the same time :retracting the stop bolt 01' latch 53. The platen is then free to be drawn forwardly out of thev machine.

It is. also an important featureof thepresent invention that the movementof the platen inwardly to operative position under the press member 52 .controls mechanism by which the press member is automatically -operated to press the marking plate upon the. work. This is accomplished by the following mechanism.

In the path of the inner end of the platen body I5 is a stem 64 (Figs. 2 and 3) adjustably fastened to an arm .65 by means of. a clamping screw 66. The arm 65 is mounted'upon a slide bar 6'! supported in a slideway' in-the'base I and is provicled atits rear'end with an abutment pin 68 which bears against'arm 65. The opposite end is shifted by a spring (not shown) toward the right to set or engage the clutch. The clutch I6 is mounted on a transversely disposed shaft I1 journaled in bearings at the top of the frame II and on this shaft 11 is loosely mounted a continuously driven pulley I8 to which one of the clutch members is fixed. When the clutch 16 is set the pulley I8 acts to rotate the shaft I1 and when the clutch is thrown out the shaft 11 is at rest.' A spring I9 (Fig. 3) acting against the shipper lever Ill yieldingly urges the upper arm I3 toward the clutch-shifting member 15 and also'acts through lever Hi to. hold the slide bar 6'! at the limit of its movement toward the right (Fig. 2). Thus the wedge I4 is normally held in position'to engage the clutch-shifting member I5 so that the clutch is normally disengaged and the'press member 52, actuated from shaft 11, is normally inactive; g

Fast on shaft 11 is aneccentric 89 connected by a pitman 8| with the upper end of the press member .52. It will be understood that the press member is mounted to slide on vertical ways pro-- vided on the frame II and is reciprocated vertically by shaft 11 and the eccentric connection when the clutch is in engagement.

When the platen I3 is shoved inwardly to the limit of its movement toward its operative position under the press member the rear end of the platen body I5 will engage the end-of stem 64, thereby moving the stem 64,'arm B5, slide bar 61 and lever Ill toward the left, as viewed in the drawings, whereupon the clutch 'lli will be engaged and the press member will be reciprocated' vertically by the eccentric 80 until the platen is again pulled forwardly out of operative relation to the press member. The inward movement of the platen is limited by the e agement of th 'arm III with the frame of the machine and the outward movement of the lever I0 in the opposite direction underthe influence of spring I9 is limited by the engagement ,of. the arm 65 on slide 61' with the rear side of the frame I0.

Thebody I5 of the platen is provided upon its under side with rollers 82 loosely mounted within rectangular pockets 83 provided on the under side of the body I5 (Figs. 4 and 5). These rollers are held against falling out of the pockets 83' when the platen is removed from the machine by strips of metal. 84 fastened by screws to the bottom of the body I5. The' rollers 'are'also held against endwise movement in the pockets 83 by small plates 85 fastened to opposite sides of the body I5. The base I 0 of the frame is made with a I plurality of parallelrunways 86. (Figs..1 and 2) on which the rollers 82 travel as the platen is moved back and forth.

The marking plate 31 isprovided on its top side with a'pad 31% (Figs. 3, 8 and-10) which may consist of a piece of cardboard of a size and shape corresponding approximately to the size and shape of the marking plate 31. This pad receives the direct impact of the" press member 52 during the marking operation. Arubber pad or similar cushion 52 may be provided on the under side of the press member 52, if desired. In practice the pad 31 may conveniently and. economically be made from the piece';of cardboard cut out from the work-positioning plate 2I to form the recess 23. This piece, which would otherwise be waste; may-be utilized as the pad by trimming it slightly to fit the marking plate and fastening it, by'cement for. example; to the top side'of the marking plate.

The operation of the machine, which will be evident from the foregoing description, may be briefly summarized as follows: When the platen is pulled. forward out of its operative relation to the press. member 52 the press member :Will be at rest or inactiveand the marking plate 31 will' beheld in raised or open position by the engagement of the arm 54 with the cam 55. The operator then'places the shoe upper'section or other article of sheet material to be operated upon in correct'position within the recess or'cut-out 23,

of the work-positioning plate 2| with the surface which is to be marked downward in contact with the marking surface of the transfer sheet 44.

, Theplaten is then shoved inwardly into operaplaten' reaches its innermost or operative posi- 7 tion under the press member; it actuates the shipper lever 19, therebysetting the clutch "I6 and causingthe' pressmember 52' to descendon top of the marking plate, whose pattern is thereby impressed on the under side'of the work by the transfersheet- 44; ordirectly on the work'if no transfer sheet'is used; When'the press member rises the platen is again manually pulled out to 12 to 16 inclusive the transverse rock-shaft 21 is made with a flat rear side provided with a is engaged by a releasable latch 93 pivoted to the rock-shaft at 94. The marking plate 31 is provided at its inner end with a perpendicular flange 39 formed with notches 94, spaced to correspond with the studs 89, so that when the marking plate is applied to the rock-shaft 21, the engagement of the notches 94 with studs 89 will properly position the marking plate and hold it against displacement. After the marking plate has been placed in position on shaft 2! the clamping bar 9| is swung downward into closed position against the flange 39 and the latch 93 is engaged with the free end of the clamping bar to hold the parts in place. This detachable connection, like the ones shown in Figs. '7 and 8, permits two or more marking plates to be attached side by side to the rock-shaft at the same time if desired.
